BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent N 0. 408,872, dated August13, 1889. Application filed February 18, 1889. Serial No. 800,353- (Nomodel.)

To all whom it may concern.-

Be it known that I, JAMES B. GOSGRAVE, a citizen of the United States,residing at Binghamton, in the county of Broome and State of New York,have invented certain new and usef ul Improvements in Bottle-Stoppersand I do hereby declare the following to be a full, clear, 7

and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

Similar letters refer to similar parts throughout the several views.

My invention is that of a bottle-stopper, designed for use onbeer-bottles and those containing aerated drinks, and for uses of likenature, where they are required to be kept air-tight and sustain greatpressure from the contents. It may also be used for fruitjars and otherreceptacles where an air-tight easily opened and closed vessel isrequired, and the method of attachment to the receptacle can be variedand adjusted to meet these varied uses.

In the accompanying drawings it is shown fitted on the commonbeer-bottle, designed to fit the bottles now in use.

Figure 1 is an elevation showing the stopper as closed down. Fig. 2shows the stopper raised to open the bottle and the bottle turned to adifferent position from that shown in Fig. 1, so as to show the mannerin which the stopper is fastened on the bottle. Fig. 3 shows a sectionof the stopper or lid on the dotted line in Fig. 2. Fig. 4 is a view ofthe blank spread out flat, and shows the several parts formed integral.

In the drawings, 13 is the neck of a common bottle, which is enlarged atthe top, as shown at B. Around the top of the bottle are the metal bandsE and F. E passes around at the top and F around at the neck below theenlargement. These are connected together by the metal strips f, whichare shaped to fit the swell of the top of the bottle, the whole beingmade preferably in a single piece. These bands E and F are fastenedHinged between the eyes of the band E is the swinging metal cover G,made to shut down inside the band E upon the top of the bottle. On theface of the cover, and fastened to it by a small bolt g and nut g, is arubber stopper A, which should be thick enough to go down firmly uponthe mouth of the bottle when the cover is shut down. Across the top ofthe cover G and turning on the bolt 9 is a bar H, made of proper lengthand thickness to turn under the hooks D D, and having flattened ends orthumb-pieces h 7L. The bolt 9 is shown as encircled by a bushing g; butit is obvious that such bushing may be dispensed with, if desired.

When the bottle is filled, the cover is shut down, the bar H is turnedaround under the hooks D D, the pressure obtained by forcing the baralong the inclined under surface of these hooks pressing the cover downfirmly and completely closing the bottle. Any inequality of surface ofthe neck of the bottle is overcome by the pressure which is brought tobear, the rubber is forced down into the neck, and the bottle ishermetically sealed. \Vhenthe bottle is to be opened, the bar H isturned from under the hooks D D, when the stopper is easily raised, ifnot forced up by the pressure from the inside.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A stopper for bottles and similar reeep- 5 tacles, consisting ofbands E and F, connected together, the said band E having projectinglugs or hooks with inclined under edges, in combination with a coverhaving upon its face ,a rubber stopper and upon the reverse side IOO abar adapted for engagement with said lugs or hooks, for the purpose setforth.

2. In a bottle-stopper, a band adapted to encircle the neck of thebottle and having hooks or lugs formed with inclined under edges, incombination with a swing-cover earrying a stopper, and a bar fulerunledon the upper surface of said swing cover and adapted to engage said lugsor hooks, substantially as and for the purposes set forth.
